Description
The Eotech PRS 2" Cantilever is a 30mm scope mount.
Ring diameter has to match the scope tube exactly. This is 30mm, so it fits a scope with a 30mm tube and no other – a ring will not close around a larger tube and will not hold a smaller one.
Height determines how high the scope sits above the receiver. It has to be tall enough for the objective bell to clear the barrel and suit the shooter's cheek weld; too tall costs a consistent head position, too low will not clear the bell at all.
Optics are not firearms. This ships directly to your address with no FFL transfer required.
